If you love comic books and love reading on your iPad, you’ve probably heard of comiXology. The company (and app) are responsible for bringing comic books into the digital age of online purchasing and reading content on a mobile device. So it was only a matter of time before it attracted the eye of the largest online source for purchasing reading material. ComiXology’s CEO, David Steinberger, posted the news on their web site Thursday afternoon that they had been purchased by Amazon.

Since 2007, comiXology has been partnering with comic book publishers to bring titles to their service, most notably the DC and Marvel lineups. In 2013 it added a service for independent comic books to self-publish their work.

Naturally, there will be concern for the fate of comiXology in the hands of Amazon, but Steinberger offered some comfort as part of his announcement;

“ComiXology will retain its identity as an Amazon subsidiary and we’re not anywhere near done “taking comics further.” We are confident that – with Amazon by our side, who shares our desire for innovation and a relentless focus on customers – we’ve only just begun.”

Very little is known about the terms of the deal, but the two companies are expected to work out the details and close the deal some time in the second quarter of 2014.
